选择贵州织金新华戈仲伍地区含稀土白云质磷块岩为研究对象; 分别研究了磷块岩主要矿物成分、化学成分、稀土组成及微量元素等含量特征; 并对主要成分胶磷矿等进行了嵌布粒度统计; 得出了该磷矿矿体中P2O5平均质量分数为20.18%; 嵌布粒度以中细粒为主; 脉石矿物主要为白云石; 稀土主要以钇(Y2O3)、镧(La2O3)、钕(Nd2O3)、铈(CeO2)为主; 占稀土总量质量分数的84.51%～85.50%; 平均85.10%; 轻稀土占稀土总量的56.97%～61.78%; 平均58.44%; 重稀土占稀土总量质量分数的38.22%～43.03%.矿石类型主要为白云质磷块岩、泥质纹层状和条带致密块状磷块岩.通过综合分析测试; 查明了矿样的矿物组成; 稀土元素的赋存状态; 为深入开展该类型磷块岩矿物加工工艺研究提供基础资料.

Abstract:
The Zhijin Gezhongwu ore zone of the Xinhua phosphorite deposit is a most important phosphor and REE enriching zone in western of Guizhou province. This study analysed the chemical composition, REE and trace elements of the ore in this area. The embedded mineral grain size distribution of main composition, phosphate rock, was statistically analysed. The average P2O5 grade of the ore is 20.18%, and phosphate particle sizes are mainly between middle and fine. The main gangue minerals are dolomite. The REE in the ore are mainly yttrium (Y2O3), lanthanum (La2O3), neodymium (Nd2O3), and cerium (CeO2) elements, which account for 84.51%—85.50% of the total REE, (average is 85.10%). Light rare earth elements account for 56.97%—61.78% of the total REE（average is 58.44%). Heavy rare earth elements account for 38.22%—43.03% of the total REE. The main types of ore are dolomitic phosphate rock, shale laminated and banded compact block phosphate rock. The mineral composition of ore samples, REE occurrence were obtained through a comprehensive analysis and test providing a basic information for this type of phosphate rock to be processed.
